{{call}} is waiting for some messages that can leak similarly as it happens in DP-112. Another problem it has is that a later call to {{call}} can pickup the result message intended for an earlier interrupted call.

As in DP-112 the most obvious fix seems to be wrapping the {{call}} definition with {{callLocal}}.
